Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

• Creates an array of points that defines a polygon.

• Creates a path and adds the polygon to the path.

• Draws the path to the screen.

private:
   void AddPolygonExample( PaintEventArgs^ e )
   {
      // Create an array of points.
      array<Point>^ myArray = {Point(23,20),Point(40,10),Point(57,20),Point(50,40),Point(30,40)};

      // Create a GraphicsPath object and add a polygon.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddPolygon( myArray );

      // Draw the path to the screen.
      Pen^ myPen = gcnew Pen( Color::Black,2.0f );
      e->Graphics->DrawPath( myPen, myPath );
   }

private void AddPolygonExample(PaintEventArgs e)
{
             
    // Create an array of points.
    Point[] myArray =
             {
                 new Point(23, 20),
                 new Point(40, 10),
                 new Point(57, 20),
                 new Point(50, 40),
                 new Point(30, 40)
             };
             
    // Create a GraphicsPath object and add a polygon.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddPolygon(myArray);
             
    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}

Public Sub AddPolygonExample(ByVal e As PaintEventArgs)

    ' Create an array of points.
    Dim myArray As Point() = {New Point(23, 20), New Point(40, 10), _
    New Point(57, 20), New Point(50, 40), New Point(30, 40)}

    ' Create a GraphicsPath object and add a polygon.
    Dim myPath As New GraphicsPath
    myPath.AddPolygon(myArray)

    ' Draw the path to the screen.
    Dim myPen As New Pen(Color.Black, 2)
    e.Graphics.DrawPath(myPen, myPath)
End Sub

Remarks

The points in the points array specify the vertices of a polygon. If the first point in the array is not the same as the last point, those two points are connected to close the polygon.

AddPolygon(PointF[])

Adds a polygon to this path.

public:
 void AddPolygon(... cli::array <System::Drawing::PointF> ^ points);

public void AddPolygon (params System.Drawing.PointF[] points);

member this.AddPolygon : System.Drawing.PointF[] -> unit

Public Sub AddPolygon (ParamArray points As PointF())

Parameters

points

PointF[]

An array of PointF structures that defines the polygon to add.

Examples

For an example, see AddPolygon(Point[]).

Remarks

The points in the points array specify the vertices of a polygon. If the first point in the array is not the same as the last point, those two points are connected to close the polygon.

AddPolygon(ReadOnlySpan<PointF>)

Adds a polygon to this path.

public:
 void AddPolygon(ReadOnlySpan<System::Drawing::PointF> points);

public void AddPolygon (scoped ReadOnlySpan<System.Drawing.PointF> points);

member this.AddPolygon : ReadOnlySpan<System.Drawing.PointF> -> unit

Public Sub AddPolygon (points As ReadOnlySpan(Of PointF))

Parameters

points

ReadOnlySpan<PointF>

An array of Point structures that defines the polygon to add.
